Corison produces Cabernet Sauvignon from St. Helena, a region in Napa Valley known for structured, age-worthy reds. The winery's portfolio centers on single-vineyard expressions: Helios Cabernet Sauvignon, Kronos Vineyard Cabernet Sauvignon, and Sunbasket Vineyard Cabernet Sauvignon. These wines have been assessed by Wine Enthusiast, Wine Advocate, Decanter, Falstaff, and Wine Spectator. Cabernet Sauvignon from St. Helena typically displays the varietal's characteristic depth—dark fruit, tannin structure, and the mineral precision that the region's volcanic soils impart. The winery's focus on vineyard-designated bottlings reflects a commitment to terroir expression within the Napa Valley appellation.
